NAILING IMPLEMENT.

Patented July 3, 1906.

Application fileil July 7,1905. Serial No. 268,696.

To all whom, it Hui/y concern:

Be it known that I, JOHN MALMGREN, a citizen of the United States, residing at Ceresco, in the county of Saunders and State of Nebraska, have invented a new and useful Nailing Implement, of which the following is a specification. v

This invention relates to nailin implements, and while especially designed for use in shingling may be used with equally satisfactory results for other purposes.

The object of the invention is to provide a nailing implement embodying new and improved features ofreliability and convenience.

A further object of the invention is to provide a nailing implement having a nail-box formed to assort and arrange nails upon the conveyer with a great degree of accuracy.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be.

hereinafter fully described, shown in the accomp anying drawings, and p articularly pointed out in the appended claims, it being understood that changes in the form, proportions, size, and minor details may be made without departing from the spirit or sacrificing any of its advantages.

In the drawings, Figure 1 is a view of the improved nailing implement in side elevation. Fig.2 is a top plan view of the improved nailing implement. Fig. 3 is a bottom planview of the nailin implement. Fig. 4 is a detail view of the c riving-head and nail-feed from the under side and with a nail in position to be set. Fig. 5 is a transverse sectional view of the nail-box on line 5 5 of Fig. 1. Fig. 6 is a transverse sectional view of the nail-conveyer, taken on line 6 6 of Fig. 1.

Like characters of reference designate corresponding parts throughout the several views.

In its preferred embodiment the nailing implement forming the subject-matter of this application comprises a driving-head 1, having a serrated driving-face 2 and a split tingknife 3 secured thereto, as by the bolt 4. Upon opposite sides of the driving-head 1 are secured the bars 5 and 6 by the bolt 4 and forming between them the nail-conveyer slot 7 and the nail-holding opening 8. The ends of the bars 5 and 6 opposite the head 1 are thereon by the bolt 10.

;. Intermediate the ends of the bar 5 a handle 11 is rigidly secured, as by the bolts 12, passing through the bracket 13. Adjacent the head 1 the bars 5 and 6 are provided with a transverse slot 14., curved to conform to the curved lower ends 15 of the'bars, and therein is mounted the feed-plate 16, curved to conform to the slot and carried upon the end of the lever 17, pivoted at 18 to the bracket 13. Upon the end of lever 17 opposite the feedplate is provided thumb-piece 19 adjacent the handle 11, and between the bracket and the thumb-piece is disposed the spring 20, arranged to hold the thumb-piece normally away from the handle and the feed-plate in position shown in Figs. 2 and 3.

The feed-plate is provided with an arcuate slot 21 and with an open-ended slot 22, communicating with the slot 21 and disposed obliquely to a radius from the pivot 18 to the slot 21. The feed-plate 16 is also provided with a nail-separating point 23 and a curved arm 24.

The nail-box is formed, as shown at Fig. 5, with the side 25 approximately level with the side 26 relative to the nail-conveyer, which is disposed nearer the side 26 than to the side 25 and forms a slot opening through the bottom of the nail-box, as shown at 27. Along the side of slot 27 adjacent side 25 a deflectorplate 28 is secured, forming throughout its length with the side.26 a substantially concave channel with the slot 27 at its bottom, as shown in detail in Fig. 5. The deflectorplate 28 extends throughout only a portion of the length of the nail-box, as shown in Fig. 2, and the side 25 of the nail-box is disposed relative to the conveyer and below the deflector-plate 28 as it approaches the lower end, so that, as shown at 29 in Fig. 5, the side .25 is curved considerably below the plate 28.

Above the conveyer and intermediate the ends of the nail-box a baffle-plate 30 is secured to the side 26 and arranged to spread out the nails 31 in their passage. The nailboX is provided with any approved form of closure, as the sliding cover 32, having the I leaving .a slot 37 between the cover and the bars for the insertion of a tool to move the nails in case the passage becomes clogged for any reason.

With the cover 32 removed, as shown in Fig. 2, nails may be placed in the nail-box to partially fill the box. By holding the'box in an upright position and oscillating it in a plane longitudinal with the box the nails will be thrown from one end of the box to the other. The motion described is the motion naturally employed in driving a nail with the driving-face 2. When the nails are trav- .-eling from the upper to the lower end of the box, by reason of the oscillation they seek to travel in the concave formed by the side 26 and the plate 28. The concavity of the side and plate will tend to turn the nails longitudinal with the box, and when so turned the pointed end of the nail will fall through the slot 27 and the head be retained by the strips 5 and 6, when they will slide by gravity downwardly through the conveyer-slot 7 and held therein by the cover 35. After the nails have passed beyond the forward end of the deflector-plate 28 they fall into the side 25, where it is curved below the deflectorplate, thus clearing from the conveyer the nails which might interfere with the free passage of the nails hanging through the conveyer-slot. Upon the return movement of. the implement the nails are returned to the rear end, from which point they slide easilyupon and over the plate 28. When the rank of nails reach the lower end of the feed, they are stopped by the feed-plate until the lever 1 7 is manipulated, when the point 23 passes between the first and second nail of therank,

. forcing the first nail to follow the slot 22, and

the remaining nails are held by the edge 24. As the feed-plate moves transversely the nail is forced downward in the slot 22 until it is engaged and held within the slot 21. and between the feed-plate and the side bar 5, as

shown in Figs. '1 and 4. The nail is then partially driven by striking the implement and the clamped nail. When the nail is set, the release of the spoon 19 will release the head of the nail, when the drivin may be completed by striking the head 0 the nail with the driving-face 2. The motion of driving will throw thenails' from one end to driving-head, and a slotted nail selecting and' clamping means arranged to separate the successively lowermost nails, and portions of the side walls of the slotted selecting means andthe nail-guide serving to clamp and hold the separate nails during the movement of the implement in a setting or partial driving of the nail, and for releasing the nail to permit the subsequent action of the driving-head thereon.

2. A nailing implement having a nailinghead and provided with a grooved guide along which nails may travel in the direction of the head, a selecting and clamping device crossing the plane of the groove, and slotted to permit the passage of the successively lowermost nails, a portion of the wall of the slot coacting with one of the walls of the groove to clamp and hold the separate nails during the preliminary setting or partial driving operation, the slot being widened to permit the release of the nail for the subsequent action of the head thereon.

3. A hand-nailing implement, including a nailing-head and nail-box, a rigid nail-conveyer extending from the box to the head and provided with a widened discharge end,

a main handle secured to the conveyer, a nailfeed comprising a pivoted lever carrying a plate provided with an arcuate slot and with a communicating slot oblique to a radial line extending from the pivot, a portion of the wall of the slot serving in connection with a portion of the nail-conveyer to hold the nails in position for-initial driving or setting, and an operating-handle carried by said lever;

4. In a nailing implement, a nailing-head, a nail-box having a nail-receiving slot, a conveyer with which said slot communicates, an arcuate plate arranged at one edge of the slot and serving to guide the nails thereinto, and a guard-plate extending across the plane of the slot and partly over said arcuate plate to assist in directing the nails into said slot.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses. I JOHN MAIJMGREN. Witnesses:
